Press needle is a kind of pin shaped needle, with flat handle, about one to two minutes long needle body and 0.3-0.9mm diameter. When used, the needle body can be pressed into the subcutaneous. It belongs to micro acupuncture needle. It is generally used for intradermal needle or ear needle, for subcutaneous embedding, and can keep the needle for a long time. In fact, press needle therapy is a branch of acupuncture and moxibustion therapy of traditional Chinese medicine, which is the development and innovation of traditional intradermal needle therapy. Press needle therapy, namely intradermal needle therapy, belongs to the floating needling and shallow needling in the traditional needling method. Shallow needling can achieve the purpose of treating diseases by regulating the Defensive Qi and stimulating the external defensive function of the body. The purpose of retaining needles is to wait for Qi or regulate qi, and finally achieve the balance of Qi and blood, yin and Yang.

From the perspective of modern medicine, cutaneous nerve endings are scattered in the skin layer. By stimulating nerve endings, press needle therapy can excite nerve endings to the central nervous system spinal cord and brain along the corresponding nerve conduction pathway, thus activating the regulation of nervous system and stimulating the release of histamine, prostaglandin, cytokines and other chemicals, which can affect blood circulation and ultimately achieve the effect of pain relief. The long-term retention of pressing needle can regulate endogenous substances through acupoint stimulation, and play a regulatory and therapeutic role on target organs through the integration of neuroendocrine immune complex network regulatory function.

It can be seen that the press needle has the following characteristics: 1. Because the press needle with very small diameter and very short needle length will not stab viscera and deep tissues, it is particularly safe in treatment. ② Because the subcutaneous nerves and capillaries are extremely rich, it is the site where acupuncture produces the best electrochemical effect, so the subcutaneous is the site with the best acupuncture effect. ③ Because the press needle buries the needle the action time to be long, and along with the movement when buries the needle, has increased the organism local self coordination, has increased the blood circulation repair, therefore greatly increased the acupuncture and moxibustion to the acupoint treatment function, thus enables it to receive the excellent curative effect.

Due to the limitation of various reasons, it is difficult to find the best time effect of acupuncture and moxibustion with universal regularity for many diseases, and it is also difficult to apply acupuncture and moxibustion at the best time for patients with disease change regularity to obtain the best curative effect. The above problems can be well solved by using all-weather continuous pressing needle embedding therapy.

A large number of studies have shown that the press needle is widely used in the following diseases: 1. Musculoskeletal system and connective tissue: cervical spondylosis, scapulohumeral periarthritis, lumbar disc herniation, knee osteoarthritis. 2. Eyes and appendages: myopia, granuloma. 3. Skin and subcutaneous tissue: acne, verruca plana. 4. Mental and behavioral disorders: insomnia, depression. 5. Gynecology: dysmenorrhea. 6. Respiratory system: hiccup, asthma, allergic rhinitis. 7. Nervous system: hemifacial spasm, blepharospasm, migraine, trigeminal neuralgia. 8. Endocrine, nutrition and metabolic diseases: lose weight.
